Randing is a process used in the manufacturing of leather shoes, boots, and other leather goods. It involves the application of a thin layer of leather or another material to the edges of the leather to protect and reinforce them. This is typically done to prevent the edges from fraying or becoming damaged during use. It is an important step in the leather goods manufacturing process because it helps to improve the durability and longevity of the product. It can also enhance the aesthetic appearance of the product by creating a clean, finished look along the edges of the leather.
